more in a raceme, large and handsome, 3-lin. diam., blue- 
purple. Sepals and petals oblong-ovate or broadly oblong, 
subacute. Column short, stout, about half as long as the 
perianth, the wing continued behind the anther but hardly as 
long as it, 3-lobed ; middle lobe short, broad, indistinctly hood- 
shaped, truncate at the top with an even or denticulate 
margin; lateral lobes longer than the middle one, erect or 
pointing forwards, flattened, the margins divided into numerous 
simple or branched fimbriz. Anther broad; connective pro- 
duced into a stout horn-like point which usually overtops the 
middle lobe of the column-wing.

This has doubtless been confused with T. pulchella, from which, how- 
ever, it totally differs in the structure of the column. In 7. pulchella the 
middle lobe of the coiumn-wing is much shorter than the anther, while 
the lateral lobes are barely as long as it, ard are irregularly toothed or 
jagged, and not at all ciliate or fimbriate. In the present species the 
middle Icbe almost equals the anther, while the lateral lobes are longer 
than it, and are provided with numerous fimbrie. T. longifolia differs in 
the smaller flowers, much longer and distinctly hooded middle lobe of the 
column-wing, and in the shorter lateral lobes, which terminate in a dense 
rounded brush of white cilia. 
T. imberbis.— Mr. R. H. Matthews sends a variety with 
cream-coloured flowers from Kaitaia (Mongonui County). 
Orthoceras strictum.—Vicinity of Westport, Townson / 
The most southern locality yet recorded. 
Prasophyllum rufum.—Vicinity of Westport, not uncom- 
mon in mossy stony places up to 1000 ft., Townson! I suspect 
that the New Zealand plant will prove to be a different species. 
to the Australian, and it is also probable that the North Island 
plant described in the Handbook under the name of P. nudum 
is distinct from Macmahon’s and Townson’s South Island 
specimens. Mr. Townson’s specimens have a broad obtuse 
lip, but in Fitzgerald’s Australian Orchids (Vol. ii, Part 4) 
the lip of P. rufwm is represented as lanceolate and acute.
